In this experimental study mainly focused the thermal property such as thermal resistance and heat transfer analysis for the air gap variations provided in between two glasses on window for the domestic purposes. Easily available surrounding air considered as the experimental mater because of its arrangements. Thermal resistance of inside, outside and glasses (both glasses have same thermal conductivity such as 0.78 W/m K) all are maintained as constant throughout the investigation. But only air gap distance increased from 2mm to 14 mm with gradual increase focused. The thermal conductivity of air considered as 0.026 W/m K. Thermal resistance and heat transfer impact with respect to the air gap between glasses were identify with the help of graphical representations.

The present study tries to bring out the reenactment of plates examination warm exchanger. Essentially, it incorporates the advancement of a numerical model to depict its function and examination. The replica, in the wake of examining in opposition to the current test information, has been fathomed to acquire the impact of different factors that includes mass stream pace, a lot of stream channels, plate setup and stream designs. Plates replica warm exchanger is being depicted by an arrangement of coherence, force and vitality conditions with various rearranging presumptions. Warm exchange rate condition has likewise been incorporated into the vitality poise condition to deal with wonders happening in that. Inside the diagnostic arrangement of the arrangement of conditions which fathom liquid stream and warmth exchange forms, the circular and allegorical differential conditions in view of introductory and limit conditions is generally new in a shut frame. Numerical arrangement of condition framework is fundamentally acquired through conditions of discretization. At the point when arrangement of conditions identify with inference related to immobile issues of twin dimensions, the pertinent technique so as to estimate into the essential two dimensional frame is prescribed.

Nowadays ensure the performance of heat exchanger is one of the toughest roles in industries. In this work focused on improve the performance of shell and tube heat exchangers by reducing the pressure drop as well as raising the overall heat transfer. This work considered as a different nanoparticles such as Al2O3, SiO2, TiO2, and ZrO2 to form a nanofluids. This nanofluids possesses high thermal conductivity by using of this increase the heat transfer rate in shell and tube heat exchanger. The selected nanofluids are compared to base fluid based on the thermophysical properties as well as heat transfer characteristics. All the heat transfer characteristics are improved by applying of nanofluids particularly higher results are obtained with using of TiO2 and Al2O3 compared to SiO2 and ZrO2. Mixing of nanoparticles increased in terms of volume percentage it will be increases the all heat transfer characteristics as well as performance of the heat exchanger.

In this research aimed to estimate the overall heat transfer coefficient of counter flow shell and tube heat exchanger. Heat transfer is the phenomenon to analysis of heat transfer from one medium of fluid to another medium of fluid, it is considered as a major role in industrial applications. Numerous heat exchangers are available, in this research considered as shell and tube heat exchanger. Overall heat transfer coefficient informed that three major factors are influenced as passing of fluid (film) media coefficient inside the tubes, circulating of fluid (film) media coefficient over in the shell, and the resistance of wall made on metal. In this study Taguchi L9 orthogonal array is executed to found the overall heat transfer coefficient with effective process parameters. Three major parameters are considered for this work are coil diameter (25 mm, 30 mm, and 35 mm), baffle thickness (15 mm, 20 mm, and 25 mm) and baffle gap (200 mm, 300 mm, and 400 mm. Baffle plate thickness is highly significant factor for this experiment.

Advances in friction materials are imposed on developing multiceramic reinforced hybrid nanocomposites with superior tribomechanical properties. The silver-based matrix metals are gained significance in various applications like bearing, ratchet, and electrical contacts due to their high frictional resistance and good thermal and chemical stability compared to traditional metals. The present research is to develop silver-based hybrid nanocomposites containing alumina (Al₂O₃) and silicon carbide (SiC) nanoparticles of 50 nm mixing with the ratio of 0 wt% Al₂O₃/0 wt% SiC, 5 wt% Al₂O₃/0 wt% SiC, and 5 wt% Al₂O₃/5 wt% SiC via the semisolid vacuum stir-cast technique. The vacuum technology minimizes casting defects and increases composite properties. The casted composite samples are subjected to study the effect of reinforcement on thermal adsorption, conductivity, diffusivity, and frictional resistance. The composite containing 5 wt% Al₂O_3np/5 wt% SiC_np is to find optimum thermal and frictional behaviour. The thermal adsorption and frictional resistance are increased by 30% and 27% compared to unreinforced cast silver. The Ag/5 wt% Al₂O_3np/5 wt% SiC_np hybrid nanocomposite is recommended for automotive friction-bearing applications.
